Abstract: Un oscillateur à commande électronique capable de fonctionner dans la plage de fréquences hf/micro-ondes, comprend un amplificateur (21) comportant un filtre à cristaux empilés (25) ainsi qu'une impédance électroniquement variable (26), telle qu'un varactor à jonction hyperabrupte, faisant partie d'une boucle à rétroaction afin de varier la fréquence de sortie de l'oscillateur par rapport à la fréquence du filtre à cristaux empilés. Dans un autre mode de réalisation dudit oscillateur, on utilise un filtre à cristaux empilés multimode (55), lequel a une réponse en forme de peigne, et l'on utilise également un second filtre à cristaux empilés à temporisation (60) dans le chemin de rétroaction, afin de produire une temporisation de phase réglable pour que ledit oscillateur fonctionne de manière commandée selon les réponses se produisant dans le peigne de réponses dudit filtre à cristaux empilés multimode.

Abstract: A method and apparatus are disclosed for making and transferring shells for cans within a ram press. The shells are formed in a two-step operation in which shell preforms are formed at a first station within the press and then transferred to second station where they are formed into completed shells. 
     The shell preforms formed in the first row are transferred along a lower transfer level within the press to the fourth row tooling, and the shell preforms formed in the second row are transferred along an upper transfer level within the press to the third row tooling. A guide (104) and chopper mechanism (102) are provided for cutting up the scrap skeleton material remaining from a sheet of material used in the formation of shell preforms in the first station, during each stroke of the press. Scrap pieces fall into scrap chamber 106, from which they are conveyed from the press.

Abstract: A construction module is described, one side of which has four slightly resilient spring leaves (6, 6') which are arranged in a tulip shape and can easily snap onto the other five side faces (2 to 5) of an identical construction module. The side faces have strips (8, 8') which can be continuous or interrupted. On the inside, the spring leaves are provided with corresponding connecting elements (7, 7', 7'') which engage behind the said strips. A connection is produced between two construction modules firstly by slight deflection of the spring leaves from their position of rest and by subsequent engagement behind the said strips. The construction modules have the advantage that they can be connected to one another or detached from one another easily and reliably even after a long time and frequent use. <IMAGE>

IPC: A61K35/14
Filed: 1991-01-24
Abstract: The development of cytolytic activity of lymphocytes can be potentiated by contacting the lymphocytes with antibody reactive witi CD28 receptor, such as 9.3 monoclonal antibody. The cytolytic activity thus potentiated is CD3 heteroconjugate-independent since targeting with a CD3 anti-target compound is not required. The development of cytolytic activity can be further potentiated by also contacting the lymphocytes with antibody reactive with anti-CD2 antibody or immobilized antibody to the CD3 receptor, or by also contacting the lymphocytes with interleukin-2. The CD28 receptor may be aggregated on the surface of the lymphocytes, as by crosslinking the antibody reactive to it on the surface of the lymphocytes. This crosslinking can be by the use of a second antibody reactive with the anti-CD28 antibody. Another aspect of the present invention is a method of adoptive therapy for treating cancer in a subject comprising the steps of : (1) contacting lymphocytes in vitro with an antibody reactive with CD28 receptor to potentiate the development of cytolytic activity of the lymphocytes to produce lymphocytes having cytolytic activity that is CD3 heteroconjugate independent; and (2) introducing the cytolytic lymphocytes into a subject to kill cancer cells.

Abstract: A PSA process for the pre-purification of air to remove water vapour and carbon dioxide prior to introduction into an air separation unit, comprises in cyclical sequence, feeding air into the bottom of bed A containing adsorbent effective to remove water vapour and carbon dioxide from the air and withdrawing purified air from the top of bed A (valves 1 and 3 open) while first regenerating bed B first by venting it to atmosphere (valves 8 and 9 open), second evacuating it (valves 8 and 10 open), and third purging it with a (nitrogen) stream from the air separation unit while continuing the evacuation (valves 6, 8 and 10 open); at the end of the purge step, passing purified air from the top of bed A into the top of bed B (valves 1, 3 and 4 open); using bed B for production of pure air (valves 2 and 4 open) while subjecting bed A to first a vent to atmosphere (valves 7 and 9 open), second evacuation (valves 7 and 10 open), and third a combined purge/evacuation (valves 5, 7 and 10 open); and then passing purified air from the top of bed B into the top of Bed A (valves 2, 3 and 4 open). The three-step regeneration sequence described above makes it possible to reduce the consumption of purge gas and reduce bed size in comparison with comparable processes known from the prior art.

Abstract: The invention relates to a method and a device for handling pulverulent fluidised-bed material enabling the clogging of the porous fluidisation wall (4, 19, 21) by non-fluidisable substances mixed with the pulverulent material to be detected and prevented. It consists in dividing the porous wall into two parts: the first part (19), placed under the feed column (15), is located at a horizontal level below that of the second part (21) which is placed under the balancing column (16); each of these parts is fed by two independent volumes (18, 20) and the fluidisation pressure difference in each of these two volumes is measured. This difference increases as a function of the clogging of the porous wall (19) placed under the feed column and enables this wall to be unclogged when the difference exceeds a set value. The invention is applicable to the fluidised-bed transportation of any product: alumina, lime, cement, metal and plastic powder, foodstuffs, etc. <IMAGE>
